It would have to be a pretty cold rock, though - however massive - making the life issue a bit of a problem for those hoping to find the Anunnaki on an habitable world with an atmosphere at this distance.

Nevertheless, Planet X is Planet X, and it's possible that a brown dwarf lies way out there at the edge of the solar system as well. It is well known that ancient Egypt was unified under one King, Menes, for the first time around 3000BCE.

That world would be cold and faint – and would push and pull at the closer objects like a distant but powerful puppeteer.

NASA's Wide-field Infrared Survey Explorer (WISE) scoured this region of space in 20 searching for a so-called Planet X and came up empty."However, WISE was looking for the tell-tale warmth of gas giants – a rocky "super-Earth", like the one Sheppard's team suggest, would be too cold for the telescope to pick up.

With no written records from this very early period, a timeline has been based on the evolving styles of ceramics unearthed from human burial sites."Now though, scientists have used radiocarbon dating of excavated hair, bones and plants, with established archaeological evidence and computer models to pinpoint when the ancient state came into existence.

Previous records suggested the pre-Dynastic period, a time when early groups began to settle along the Nile and farm the land, began in 4000BC.

Additionally, I've been compiling a monthly blog full of news, links, videos and comment relating to Planet X, and various other items of interest, to run alongside the Dark Star website on

The Dark Star Blog is now over 3 years old, and has many regular readers.

Until very recently it was thought that the land along the Nile had been originally settled by farmers about 1000 years before that.

As someone interested in the ideas of author Zecharia Sitchin, I always found it curious that Egypt's chronology did not fit closer with the return of the planet Nibiru to our skies, which Sitchin claimed to have occurred around 3760BCE.

Yet, as is indicated above, it is indeed possible at the kind of distances we are discussing here.
